Dr. Jonathan Hilmer (MSU) will present “Identification of Human Remains Using Mass Spectrometry”
We currently take DNA fingerprinting for granted: in modern form it began in 1984, and it is currently a centerpiece of modern forensics. However, DNA fingerprinting will be forever subject to the physical limitations of DNA itself. While DNA can be amplified and is relatively easy to manipulate, it is also extremely fragile and present in low copy numbers. In comparison, proteins are very difficult to handle and study, but are present in great abundance and withstand harsh environmental conditions very well. A recent study by Glendon Parker and performed in collaboration with MSU was the first to show that proteins could be used to generate identity discrimination similar to DNA, representing a major breakthrough for modern forensics (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0160653). This study and the analytical techniques will be discussed.
